陳述句是復合句的反意疑問句

一、一般原則

在通常情況下，陳述句是主從復合句時，簡略問句的主語和助動詞要與主句保持一致。如：

She said that I did it, didn't she? 她說是我干的，是嗎？

They know how much it cost, don't they? 他們知道這花了多少錢，是嗎？

二、特殊情況

當陳述句部分是I believe / think / suppose 等加賓語從句時，簡略問句與賓語從句一致，但要注意否定轉移。如：

I think that he is wrong, isn't he? 我認為他錯了，是嗎(他錯了嗎)?

I don't think he likes it, does he? 我認為他不喜歡它，是嗎(他喜歡嗎)?

I don't suppose he will come, will he? 我想他不會來了，是嗎?
